Question 964413
Call the two digits a and b. Then the number written ab (think of 12 for instance) is 10*a + b.

First statement then becomes 10*a + b + 2*a = 33
Second statement is 10*a + b + 63 = 10*b + a 

Rewrite second statement as 9*a + 63 = 9*b or a + 7 = b

Plug into first statement 12*a + a + 7 = 33
or 13*a = 26
a=2
b then is 9
The number is 29.
